15 Figure 11. File Feed 7. With the magnet armature attracted and the keeper behind the drive arm, set the index to 315' i 1' and tighten clamped hub. 8. Feed a card in by turning the picker knife cam shaft until card is against first set of feed rolls. 9. Turn machine to 221' and install clutch drive belt and adjust the idler pulley. 10. Install the other three belts and unblock the clutch armature. 11. Check the following timings: a. Clutch engagement time (315' &lo) b. Brush impulse CB timing (Use CE aid panel) c. Timing of the RCCB's. File Feed Principles of Operation (Figure I I ) The file feed consist of two basic units: 1. Upper magazine 2. Lower magazine The upper magazine is the tray which holds up to 3,000 cards to be fed into the hopper. This tray is hinged and can be locked at an angle to make the brush area of the machine more accessible. The lower magazine contains clutch controlled feed rolls that feed the cards into the hopper. Operation of the helical spring-type feed roll clutch is controlled by the level of the cards in the hopper. Under spring tension, the front joggler applies pressure on the joggler operating lever, causing the lever to follow the contour of the front joggler cam. As the front joggler cam rotates, the front joggler oscillates, joggling the cards into position. If there are sufficient cards in the hopper to cover the sensing pads, the inward travel of the joggler is limited and the joggler control lever is not allowed to follow the low dwell of the front joggler cam. There will be no clutch action or cards fed down into the hopper at this time. When the card level drops below the sensing pads, the additional travel of the joggler forces the joggler operating lever to follow the low dwell of the front joggler cam. At this time, the tab on the joggler operating lever will cause the clutch operating lever to rotate counterclockwise, pivoting the clutch latch out of the step in the clutch sleeve. The helical spring grips
